Field of the invention
[0001] The present invention refers to a tamper-evident container and to a process for making
the same. The container can find an application, generally, in all the fields which
provide to wrap finished products for ensuring the closure of the container itself
and provide a safety which enables to give evidence, also to sight-impaired persons,
of a possible tampering of this latter. Specifically, the container, object of the
present invention, can find an advantageous application in the pharmaceutical and
cosmetic fields, for example for defining portable dispensers able to house tablets
or pills because, in such fields, it is of importance to ensure the provision of intact
and in any way unaltered products.
Background of the invention
[0002] It is known the use of containers of paper or plastic material, provided with safety
systems configured for providing evidence of a tampering of the container itself.
These containers, called also "tamper-evident" containers, are configured for enabling
to insert products inside them and, then in a first closed condition, enabling the
activation of the safety device - in the field the activation of the safety device
is generally called as an "arming device" condition - so that, following a first open
condition, the container can provide evidence. These systems are generally used in
the pharmaceutical, cosmetic and food fields, in which it is particularly important
ensuring the provision of intact products and in compliance with the specifics indicated
on the container.
[0003] For example, boxes or containers of paper or plastic material which use as "tamper-evident"
systems, additional wrappers of plastic material adapted to wrap the whole box to
define a substantially further envelope, are known. These boxes exhibit several limitations
and disadvantages; de facto, the further packaging appears to be particularly expensive
because it provides the use of additional raw materials (an additional plastic film)
and requires a high number of steps for sealing the box: additional steps of predisposing
and applicating the film. Besides the economical disadvantages caused by the further
packagings, these are not capable of providing evidence of a tampering of the pack;
de facto, the distributor could easily remove the plastic film for altering or substituting
the products in the container and proceed with the sale of this latter without the
further safety wrapper by offering to the public only the pack (the unpackaged container).
[0004] Further, boxes made of paper or plastic material using, as "tamper-evident" systems,
seals and/or labels configured for holding closed the box itself, are known. This
last kind of safety system is certainly more efficient than the above described further
wrappers because removing the seal would not enable to correctly reclose the box and
consequently it would be possible to provide evidence of a tampering of the container
to the customer. While these latter described boxes are an improvement with respect
to the above described containers with a further wrapper, such boxes are however particularly
expensive because they also require additional raw materials represented by the seals/labels
and additional steps for predisposing and applicating such elements. For this reason,
"tamper-evident" containers of paper material improved with respect to the above described
ones, have been made.
[0005] A first example, described in the USA patent application
US2011/0180537A1, refers to a box completely made of paper material, having a storehouse provided
with an opening delimited by a free edge; at such opening there are two opposite lateral
tabs rotatingly moveable around the edge. The lateral tabs are configured for rotating
inside the storehouse and placing themselves in a partially overlapped condition.
Each of said tabs is notched at the storehouse free edge to define a kind of moveable
door. Further, the container exhibits a cover engaged with the free edge of the storehouse
and interposed between the tabs; the cover is also rotatingly moveable around the
free edge and is configured for being positioned above the tabs. Specifically, the
cover carries a closure tab adapted to be overlapped on the lateral tabs to define
a closed condition of the container; further the cover carries an engagement tab adapted
to enter inside the container and to be locked to the lateral tabs for holding said
closed condition. The closure tabs exhibit notches defining the doors, which are configured
for cooperating with the lateral tab doors. The container provides, as a tamper-evident
system, to forcedly fold inside the storehouse the closure tab and lateral tabs doors:
the opening of the container causes the breakage of the doors carried by the closure
tab.
[0006] The container, described in the US application, is an improvement with respect to
the above described packaging and sealing systems at least with reference to the product
and process costs. De facto, the container described in such application, is entirely
made of paper material: the tamper-evident system is formed by paper portions of the
closure tab and of the lateral internal tabs. For this reason, the containers, described
in the USA application, are more advantageous in terms of costs because they do not
provide the use of additional materials (for example coverings of plastic film and/or
further labels) and the additional process steps for predisposing and applicating
such material. For example, the container, as described in the USA application, exhibits,
with respect to the process of forming the standard (non tamper-evident) containers,
the additional steps of notching the tabs and a further step of folding the doors
inside the storehouse. Naturally, the necessity of executing the additional process
steps with respect to the simple implementation of the container (the box without
the safety device), provides that also the plant for producing such boxes is provides
with additional components destined to perform the required additional steps for predisposing
the safety device: therefore the plant requires further toolings. It is evident that,
besides the product and process costs, the paper boxes, described in the USA application,
will entail further expenses for tooling the plant. It is further useful to detect
that the complex structure of the container, besides requiring a particularly tooling
of the production plant, requires suitable toolings of the packaging plants dedicated
to insert products inside the container and the following closure of the same. De
facto, the structural complexity of the above described container, burdens both on
the production plant and on the container packaging one with a consequent substantial
increase of the costs of the entire packaged product.
[0007] A further inconvenience of the described box of the prior USA application, is represented
by the tamper-evident system structure, which is easily penetrable; de facto the safety
device is positioned on the top of the container and at the box free edge: the safety
device itself could be tampered and bypassed at the container opening in order to
avoid breaking the doors and therefore without giving evidence of any tampering.
[0008] A second example, described in the European patent application
EP0519389A1, relates to a box entirely made of paper material exhibiting substantially the same
structure as the container described in the first example (USA application). Also
such container exhibits a storehouse provided with an opening delimited by a free
edge; at such opening there are two lateral tabs opposite to each other and rotatingly
moveable around the edge. The lateral tabs are configured for rotating inside the
storehouse and being placed in a partially overlapped condition. As opposed to the
USA application, each tab exhibits, at the overlapping area with the other tab, a
removable portion provided with an undercut. Further, the container exhibits a cover
engaged with the storehouse free edge and interposed between the tabs; the cover is
also rotatingly moveable around the free edge and is configured for being placed above
the tabs. Particularly, the cover carries a closure tab adapted to overlap with the
lateral tabs to define a container closed condition; the cover further carries an
engagement tab adapted to enter inside the container and to be locked to the lateral
tabs for maintaining said closed condition. The closure tab exhibits a notch adapted
to define a seat suitable for receiving the undercut of the tabs removable portions.
The container provides, as a tamper-evident system, the joint of the removable portions
inside the cover seat during the first container closure; the container opening causes
the removal portions carried by the inner lateral tabs to be torn.
[0009] As per the USA application, the container, described in the European application,
is an improvement with respect to the above described packaging and labeling systems
at least with reference to the product and process costs. De facto, the container,
described in such application, is also entirely made of paper material: the tamper-evident
system is only formed by paper portions of the lateral internal tabs (it is not provided
the use of an additional material and additional process steps for providing and applying
said material). However it is observed that the container, described in the European
patent, is an improvement with respect to the first example because the box/container
"arming" is done at the first closure of the same, without requiring further steps
of notching and folding the box. For this reason, the second example exhibits a manufacturing
process faster and more cost-effective than the one described in the USA patent.
[0010] However, it is observed that, also the tamper-evident system, described in the second
example, is easily bypassable because it is placed on the top of the container; also
in this case, it is could be possible to bypass the safety device by tampering the
container without causing the breakage of the removable portions (therefore without
providing evidence of tampering).
[0011] Further, it is noted that all the above described tamper-evident systems are not
configured for providing evidence of a container tampering to sight-impaired people;
de facto, all the above described systems use, for giving evidence of a first container
opening, only a visible device preventing the sight-impaired people to verify the
container condition.
Object of the invention
[0012] Therefore it is an object of the present invention to substantially solve at least
one of the disadvantages and/or limitations of the preceding solutions.
[0013] A first object of the invention consists of providing a container which can effectively
ensure to give evidence of tampering at a first opening of the container itself, also
to sight-impaired people. A further main object of the invention consists of providing
a tamper-evident container which can ensure an easy and effective arming at a first
opening of the container itself. A further main object of the invention consists of
providing a container which is easy and fast to manufacture, which enables to reduce
at the minimum the manufacturing and product costs. Another object of the invention
consists of predisposing a container which is substantially capable of offering an
optimal attractive appearance and, at the same time, of maintaining a simplification
of the manufacturing and assembly processes. Then, it is a secondary object of the
invention to predispose a tamper-evident container which can be used several times
by an user and therefore can be disposed by recycling it, once exhausted its task,
without particular problems due to the unbiodegradability of the material by which
is made of.
[0014] One or more of the above described objects which will be better appear in the following
description are substantially met by a tamper-evident container and by a respective
manufacturing process according to one or more of the attached clams.

Detailed description
Tamper-evident container
[0159] 1 generally shows a tamper-evident container for containing and supporting products.
In the present description, we will not go into detail on the type of useable products
because such container 1 can find an application, generally, in all the fields providing
the packaging of products in order to ensure the closure of the container itself and
providing a safety enabling to give evidence of a possible tampering of this latter.
Particularly, the container object of the present invention can find an advantageous
application in the pharmaceutical and cosmetics field, for example, for defining dispensers
able to receive tablets or pills; de facto, in such fields it is particularly interesting
to provide intact products and in anyway altered and consequently it is of interest
the use of containers capable of giving evidence of a possible tampering or first
opening.
[0160] As it is for example visible in Figures 1-4 and 27-31, the container 1 comprises
at least one storehouse 2 defining an internal volume 3, configured for housing products,
for example tablets, pills or blisters (the products are not shown); the storehouse
2 substantially represents the compartment able to house and support the products.
More specifically, the storehouse 2 comprises a predetermined number of lateral walls
4 defining at least one passage opening 5 delimited by a free edge 6: the passage
opening 5 is configured for communicating the storehouse 2 internal volume 3 with
the external environment. The attached figures illustrate, in a non limiting way,
a configuration of the storehouse 2 exhibiting two through opening 5 opposite to each
other with respect to the storehouse 2 itself so that this latter could define substantially
a conduit or tube laterally delimited by said walls 4 and opened at the longitudinal
ends. However, it is not excluded the possibility of forming, for example, a storehouse
2 exhibiting only one passage opening 5 or even a number of openings 5 greater than
two (these conditions are not illustrated in the attached figures).
[0161] The attached figures illustrate a preferred but non limiting configuration of the
storehouse 2 exhibiting a rectangular prismatic shape (the flat lateral walls 4 having
a rectangular shape). However, it is not excluded the possibility of forming a storehouse
2 having a different shape, for example a square, trapezoidal or cylindrical one.
As it is visible, the storehouse 2 extends, in a non limiting way, substantially along
a prevalent development direction and exhibits a thickness smaller with respect to
the length and width of the same. The storehouse 2 is configured for exhibiting a
minimum size, in this case the thickness, greater than a maximum transversal size
of each product; the minimum size of the storehouse 2 is, in a non limiting way, greater
than 7 mm (the thickness can vary and be suitable sized based on the product and quantity
to be contained/supported). The invention provides small sized containers 1 whose
storehouse 2 defines an internal volume substantially greater than 20,000 mm
3, particularly comprised between 40,000 and 200,000 mm
3. However, the container 1, object of the present invention, can be used for packaging
medium sized products; under such condition, the storehouse 2 can exhibit an internal
volume 3 greater than 500,000 mm
3, particularly comprised between 800,000 and 1,400,000 mm
3. However, it is not excluded the possibility of using the container 1, object of
the present invention, for packaging large sized products; under such condition, the
storehouse 2 has an internal volume 3 greater than the above specified volumes, for
example greater than 10,000 cm
3.
[0162] As it is for example visible in Figures 1, 8 and 31, the storehouse 2 can comprise
at least one control through opening 24 substantially placed at the free edge 6 of
the passage opening 5. Figures 1, 8 and 31 illustrate a configuration of the opening
24 which defines a closed perimetral edge and distanced from the storehouse free edge
6; the opening 24 exhibits, in a non limiting way, a cylindrical (Figure 1), rectangular
(Figure 21), elliptical or square shape. Alternatively, the opening 24 can exhibit
an open perimetral edge defining at least partially the free edge 6 (see Figure 22,
for example): in such configuration, the opening 24 substantially comprises a through
recess. The attached figures illustrate a non limiting configuration of the container
1 wherein the opening 24 exhibits a substantially "V" shape whose concavity faces
oppositely the storehouse 2 internal volume 3. The particular function of the opening
24 will be better described hereinafter.
[0163] As it is visible for example in Figures 1, 5, 33 and 35, the storehouse 2 can further
comprise, at the free edge 6, a recess 27; as it is visible in the attached figures,
the recess 27 is in contact with the free edge 6 for defining on this latter a kind
of depression. Advantageously, the recess 27 is defined on the storehouse 2 lateral
wall 4 on which it is further present the opening 24 and particularly on the lateral
wall 4 able to abut directly on a closure device 7 of the container 1 which will be
better described hereinafter. The recess 27 exhibits an open perimetral outline which
exhibits a substantially "C" or "V" or "U" shape, whose concavity faces oppositely
the storehouse 2 internal volume 3. At a dimensional level, the recess 27 defines
a depression of the free edge 6 having a maximum depth greater than 1 mm, particularly
comprised between 2 and 10 mm; the maximum depth is represented by the maximum distance
between the free edge and the bottom edge of the recess 27.
[0164] The storehouse 2 is made of sheet material and is obtained for example by folding.
In a preferred but non limiting embodiment of the invention, the storehouse 2 is made
of paper sheet material (paper or paperboard); particularly, the used sheet material
exhibit a grammage comprised between 100 and 500 gr/m
2, particularly comprised between 200 and 400 gr/m
2. As hereinbefore described, the container 1, particularly the storehouse 2, can further
be used for housing products of the pharmaceutical, cosmetic and food fields. Therefore,
it can be advantageous to cover an internal surface of the storehouse 2 by a plastic
material coating, for example a film. The coating has the object to define a barrier
interposed between the storehouse 2 and the plurality of products; the coating can
be further used for defining a water and/or humidity barrier useful for avoiding the
weakening and the loss of structurality of the storehouse with following warping of
the paper material forming this latter component. Advantageously, the coating could
comprise an extrusion coating on one (the storehouse 2 internal side) or on both the
sides (the storehouse 2 internal and external surfaces) of the paper material defining
the storehouse 2 with values which can for example vary between 10 and 50 gr/m
2 of the coating material (in other words, polyethylene). The coating plastic material
can comprise for example one selected among the following materials: LDPE, HDPE, PP,
PE.
[0165] As it is visible in the attached figures, the container 1 further comprises at least
one closure system 7, also made of sheet material, engaged at the free edge 6 and
movable, particularly by rotation, with respect to the storehouse 2. Specifically,
the closure system 7 is configured for defining at least one closed condition (see
for example Figure 1) in which the system 7 itself interdicts the communication between
the internal volume 3 of storehouse 2 and the external environment; further, the closure
system 7 is configured for defining at least one open condition (see Figures 2, 21
and 22, for example), wherein the system 7 itself enables the communication between
the internal volume 3 and external environment. De facto, the system 7 substantially
represents a cover able to cooperate with the storehouse 2 in order to manage the
access to the internal volume 3. Advantageously, the container 1 comprises a closure
system 7 for each passage opening 5 of the storehouse 2. In the attached figures,
it is illustrated, in a non limiting way, a container 1 configuration exhibiting two
through openings 5; under such condition, the container 1 exhibits two closure systems
7 engaged with the respective free edge 6 of the storehouse 2: the systems 7 are placed
opposite to each other with respect to the storehouse itself. Advantageously, the
closure system 7 is, in a non limiting way, integrally joined to the storehouse 2,
particularly with the free edge 6, and is rotatingly movable around this latter between
at least the closed and open conditions.
[0166] More specifically, the closure system 7 comprises at least one tab 7 exhibiting a
closing portion 9 directly engaged with and integrally joined to the storehouse 2
free edge 6: the closing portion 9 represents the component of the tab 8 configured
for interdicting the passage through the opening 5 under the closed condition of the
system 7 itself. As it is visible in the attached figures, the closing portion 9 substantially
comprises a flat body of sheet material countershaped to the opening 5 free edge 6.
The attached figures schematically show a preferred configuration of the closing portion
9 exhibiting a rectangular shape entirely countershaped to the free edge 6.
[0167] Further, the tab 8 exhibits at least one inserting portion 10 configured to insert,
under the system closed condition, inside the storehouse 2 volume 3. The inserting
portion 10 is integrally joined to the closing portion 9 and emerges from this latter
from the opposite side of the storehouse 2: the inserting portion 10 substantially
represents an extension of the closing portion 9 able to be inserted, under the system
7 closed condition, inside the storehouse 2. As it is visible in the attached figures,
also the inserting portion 10 comprises substantially a flat body made of sheet material
having, in a non limiting way, a rectangular shape. As it is visible, for example,
in the cross-section view in Figure 8, the inserting portion 10 extends between a
first and second prevalent development surfaces 10a, 10b respectively outwardly facing
(directly facing a storehouse 2 lateral wall 4) and towards the storehouse 2 internal
volume 3. Under the closed condition of the system 7, at least one portion of the
first development surface 10a of the inserting portion 10 faces, particularly contacts,
directly a part of a storehouse 2 lateral wall 4: the surface 10a extends at least
partially parallelly to the storehouse 2 wall 4, particularly parallel to a storehouse
2 front wall opposite to the wall directly connected to the system 7 (definable also
as the storehouse 2 back lateral wall).
[0168] The closing portion 9 and the inserting portion 10 exhibit a reciprocal connection
edge opposite to the storehouse 2 free edge 6 with respect to the closing portion
9 itself: the inserting portion 10 is rotatingly movable with respect to the closing
portion 9 around said reciprocal connection edge. As it is visible for example in
Figure 8, the inserting portion 10, under the system 7 closed condition, is configured
for defining, according to a cross-section and in cooperation with the closing portion
9, a substantially "L" shape: under such condition, the inserting portion 10 substantially
extends parallel to one storehouse 2 lateral wall 4.
[0169] As it is visible for example in Figures 2-5, 21-25, 27 and 34, the closure system
7 further comprises at least one abutment portion 11 engaged with the storehouse 2
free edge 6 adjacent to the tab 8: the abutment portion 11, under the closed condition,
is configured for being interposed between the internal volume 3 and tab 8 in order
to cooperate with this latter for holding stably it in said closed condition. The
abutment portion 11 substantially comprises a flat tab made of sheet material integrally
joined to the storehouse 2 free edge 6 adjacent to the closing portion 9. The abutment
portion 11 exhibits, in a non limiting way, a rectangular or trapezoidal shape. Also
the abutment portion 11 is configured for rotating around the free edge 6 for facing,
at least under the container 1 closed condition, the storehouse 2 inside. More particularly,
the abutment portion 11 is constrained to the free edge 6 in order to be capable of
engaging, under the container 1 closed condition, at least a part of the inserting
portion 10 and/or of the closing portion 9 for stably holding the tab 8 in said condition.
[0170] Advantageously, the container 1 comprises two abutment portions 11 opposite to each
other with respect to the tab 8: this latter is interposed between the two abutment
portions 11. In such configuration (illustrated for example in Figure 2-5 and 21-25),
the two portions 11 symmetrically operate on the tab 8 for stably holding it in the
closed condition. As hereinbefore described, the storehouse 2 comprises a control
through-opening 24; as it is visible for example in Figure 8, the control opening
24 is placed on the lateral wall 4 configured for directly facing the inserting portion
10, particularly the first surface 10a of said portion 10. The control opening 24
is therefore placed in proximity with the first surface 10a and is configured to enable
visualising this latter in determined operative conditions of the container 1, which
will be better described herein below. The opening 24 can - in addition or alternatively
- be configured to enable visualising the inserting portion 10 and the correct insertion
of the same inside the storehouse 2 as it will be better described herein below.
[0171] Further, as hereinbefore described, the storehouse 2 comprises a recess 27; as it
is visible for example in Figures 5 and 29, the recess 27 is placed on the lateral
wall 4 configured for directly facing the inserting portion 10, particularly the first
surface 10a of said portion 10. The recess 27 is therefore placed in proximity with
the first surface 10a and is configured to enable visualising this latter in determined
operative conditions of the container 1, which will be better described herein below.
[0172] As it is visible in the attached figures, the closure system 7 can comprise, in a
non limiting way, a through opening 26 configured to place, under a closed condition
of the system itself, at the free edge 6, particularly at the recess 27. De facto,
the through opening 26, under the closure system 7 closed condition, is placed at
the storehouse 2 recess 27 (Figure 33): particularly, under such condition, the opening
26 and recess 27 are reciprocally facing and at least partially countershaped with
each other.
[0173] As it is visible in the attached figures, the trough opening 26 defines a closed
perimetral outline, particularly exhibiting at least one shape selected in the group
among the following shapes: rectangular, square, circular, elliptical, semicircular,
triangular. The through opening 26 is defined on the closing portion 9 and/or on the
inserting portion 10 of the tab 8. In a preferred, but non limiting embodiment of
the invention, the through opening 26 is defined, without interruption, at least partially
on the closing portion 9 and at least partially on the inserting portion 10 of the
tab 8: the opening 26 is substantially defined on the folding lines of the portions
9 and 10 of tab 8 (Figure 30).
[0174] In a preferred but non limiting embodiment of the invention, the system 7 is made,
at least partially, particularly entirely, of paper sheet (paper or paperboard); the
used sheet material exhibits a grammage comprised between 100 and 500 gr/m
2, particularly comprised between 200 and 400 gr/m
2. Optionally, the paper sheet material used for the embodiment of the system 7, is
as the sheet material used for the embodiment of the storehouse 2, particularly they
are both obtained from only one paper material sheet. As hereinbefore described, the
container 1 can also be used for housing products of the pharmaceutical, cosmetic
and food fields. Under such condition, it could be advantageous to cover an internal
surface of the system 7 by a plastic material coating, for example a film. The coating
has the object of defining a barrier interposed between the system 7 and the products;
further, the coating is able to define a water and/or humidity barrier useful for
avoiding the weakening and the loss of structurality of the system with a consequent
warping of the paper material forming this latter component. Further, it is noted
that a structurality loss or a simple warping of the closure system could compromise
the functionality of the system 7 and therefore prevent a correct closure of the storehouse
2. Advantageously, the coating could be an extrusion coating on one (internal side
of the system 7) or on both the sides (the system 7 internal and external surfaces)
of the paper material defining the system 7 with values which can for example vary
from 10 to 50 gr/m
2 of the coating material (in other words, polyethylene). The coating plastic material
can be for example selected among the following materials: LDPE, HDPE, PP, PE.
[0175] As it is visible for example in Figures 2-5 and 27-29, the container 1 further comprises
at least one safety device 12, made of sheet material, stably engageable at least
partially with the storehouse 2 and at least partially with the closure system 7 following
a first closed condition of this latter. De facto, the safety device 12 comprises
at least one removable portion 15 configured for defining, following the first closed
condition, a tactilely perceivable projection 25 (Figures 27-29) emerging from the
storehouse 2 and/or from the closure system 7: the removable portion 15, together
with the projection 25, is configured to separate from the safety device 12 following
a closure system 7 first open condition following the first closed condition for providing
evidence of a container 1 tampering.
[0176] More particularly, the removable portion 15 projection 25, under the closure system
7 first closed condition and before the container 1 first open condition, lies on
a plane parallel to the inserting portion 10 and projects from the storehouse 2 free
edge 6, particularly transversally to the closing portion 9. Still more particularly,
the projection 25, under the closure system 7 first closed condition and before the
container 1 first open condition, is configured to place at the recess 27 and emerging
besides this latter and/or besides the storehouse 2 free edge 6.
[0177] De facto, the projection 25, under the closure system 7 first closed condition and
before the container 1 first open condition, is configured for substantially remaining
flush with the tab 8 closing portion 9 or is configured for emerging transversally
from said closing portion 9; anyway, the projection 25, in both the configurations,
is able to be tactilely perceivable so that the same can be distinguishable from the
closed portion 9, the free edge 6 and from the recess 27. From the geometrical point
of view, the projection 25 exhibits, according to a front view normal to the lying
plane of the projection 25 itself, a shape selected in the group comprised among:
triangular, square, rectangular, trapezoidal, semicircular, elliptical shape. In a
preferred but non limiting embodiment of the container 1, the projection 25 exhibits,
according to front view normal to the lying plane of the projection 25 itself, a tapered,
particularly triangular, shape extending from the storehouse 2 free edge 6: the projection
25 tapered shape is configured for assisting the tactile perception of the same during
the closure system 7 first closed condition and before the container 1 first open
condition. From the quantitative point of view, the projection 25 extends besides
the free edge 6 to an extent greater than 1 mm, particularly between 1 and 10 mm,
still more particularly between 1 and 7 mm. The tapered shape and the height of the
projection with respect to at least the storehouse 2 free edge 6 enable an easy and
fast tactile perception of the same projection for example by passing a finger on
the tab 8 closing portion 9.
[0178] The attached figures illustrate a preferred but non limiting embodiment of the safety
device 12 exhibiting at least one first coupling portion 13 carried by the tab 8 and/or
by the abutment portion 11, and at least one second coupling portion 14 engaged with
the storehouse 2. The first and second coupling portions 13, 14 are configured to
stably engage with each other during a closure system 7 first closed condition in
other words during a system 7 first absolute closure wherein there is the first insertion
of the inserting portion 10 inside the storehouse 2. As it is visible in the attached
figures, the second coupling portion 14 is arranged internally of the storehouse 2
and substantially lies in a plane parallel to one of the lateral walls 4: under the
system 7 closed condition, the first coupling portion 13 is configured to insert at
least partially in the storehouse 2 internal volume 3 for stably engaging the second
coupling portion 14. The first and/or second coupling portions 13, 14 comprise at
least one removable portion 15 carrying the projection 25, configured to separate
from the safety device 12 following a closure system 7 first closed condition, following
said first closed condition, for providing evidence of a container 1 tampering. The
attached figures illustrate, in a non limiting way, a container 1 configuration wherein
the first coupling portion 13 is engaged with, particularly directly carried by, the
closure system 7 tab 8 (alternatively, it could be further carried by at least one
abutment portion 11). Advantageously, the first coupling portion 13 is carried only,
but not in a limiting way, by the inserting portion 10 of the tab 8: the two portions
10 and 13 are advantageously integrally joined to each other to form only one body.
De facto, the first coupling portion 13 comprises a flat sheet body emerging, particularly
without interruption, from the inserting portion 10 oppositely to the closing portion
9: the inserting portion 10 therefore is interposed between the closing portion 9
and the coupling portion 13. The first coupling portion 13, under the system 7 closed
condition, and therefore during the insertion of the inserting portion 10 in the storehouse
2, is configured to also insert in the internal volume 3.
[0179] The sheet material body of the first coupling portion 13 extends between a first
and second prevalent development surfaces 13a, 13b (Figure 8) respectively facing
in the same direction of the first and second surfaces 10a, 10b of the inserting portion
10: the first surfaces 10a, 13a are a continuation of each other and directly face
a same lateral wall 4 of the storehouse 2 opposite to the lateral wall 4 directly
connected to the system 7. The second surfaces 10b, 13b are also a continuation of
each other and face the storehouse 2 internal volume 3.
[0180] More specifically, the first coupling portion 13 comprises at least one undercut
portion 20 delimited by a gripping edge 21: the undercut portion 20, under the container
1 first closed condition, is configured for engaging the second coupling portion 14
arranged internally of the storehouse 2 (particularly, the second coupling portion
is completely contained in the storehouse 2).
[0181] As it is visible for example in Figures 5, 21 and 22, the undercut 20 comprises at
least one hook 22 defining a seat 23 whose concavity faces, at least during the device
12 first closed condition, at least one of the storehouse 2 lateral walls 4, particularly
faces the abutment portion 11 of the closure system 7. The undercut portion 20 seat
23 defines a substantially "C" shape: the respective gripping edge 21 delimits a portion
of said seat 23 which, under the system 7 first closed condition, faces the storehouse
2 free edge 6.
[0182] The attached figures show a preferred but non limiting configuration of the first
coupling portion 13 substantially comprising two hooks 22 opposite to each other with
respect to the first portion 13 itself. Under such condition, therefore the first
portion 13 comprises two respective undercut portions 20 which, at least under the
container 1 first closed condition, are configured for both engaging with the second
coupling portion 14. The two undercut portions 20 comprise respective seats 23 whose
concavities face away from each other: the concavities of the seats face the respective
storehouse 2 abutment portions 11. The presence of the two undercuts 20 substantially
defines a double symmetrical grip on the second coupling portion 14 which makes more
effective and stable the coupling between said first and said second coupling portions
13, 14.
[0183] As previously described, the second coupling portion 14 of the device 12 is directly
engaged inside the storehouse 2. Particularly, the second coupling portion 14 is directly
connected to at least one storehouse 2 lateral wall and extends parallelly to this
latter: the coupling portion 14 develops parallelly to the lateral wall configured
for directly facing the inserting portion 10 at least during the system 7 closed condition.
De facto, the coupling portion 14 extends parallelly to the lateral wall 4 opposite
to the wall directly connected (integrally joined to) to the closure system 7.
[0184] As it is visible for example in Figures 2, 4, 24-26, the second coupling portion
14 is integrally joined to storehouse 2, particularly is integrally joined to at least
one storehouse 2 lateral wall. As for the first coupling portion 13, also the second
portion 14 comprises a flat sheet material body emerging, particularly without interruption,
from a storehouse 2 lateral wall 4: the second portion 14 substantially defines a
sheet engaged, particularly integrally joined to, inside one or more storehouse 2
lateral walls 4. The sheet material body of the second coupling portion 14 extends
between a first and second prevalent development surfaces 14a, 14b (Figure 8) respectively
facing the outside and inside of the storehouse 2: the portion 14 first surface 14a,
at least under the system 7 closed condition, is parallel to and faces as the first
surfaces 10a, 13a (the first surfaces 10a, 13a, 14d directly facing a storehouse 2
lateral wall 4 opposite to the lateral wall 4 directly connected to the system 7).
[0185] In the configuration illustrated in the attached figures, the second coupling portion
14 comprises, in a non limiting way, the removable portion 15, carried by the projection
25, made of sheet material which extends between a first and second surfaces 15a,
15b (Figure 8) respectively facing a storehouse 2 lateral wall 4: the surfaces 15a,
15b of the removable portion 15 substantially represent a prolongation of the surfaces
14a, 14b of the second coupling portion 14, while the projection represents a respective
prolongation of the removable portion placed oppositely to the portion 14.
[0186] The removable portion 15 comprises at least one undercut portion 16 which is configured
for engaging, under the safety device 12 first closed condition, the respective undercut
portion 20 of the first coupling portion 13. The undercut portion 16 of the removable
portion 15 is delimited by a gripping edge 17 which, under the container 1 first closed
condition, is distinct and distanced from the storehouse 2 free edge 6: the undercut
portion 16 is inside the storehouse 2 (completely inside the storehouse) and distanced
from the passage opening 5 (distanced from the free edge 6) so that the removable
portion 15 can engage, under the first closed condition, the respective undercut 20
of the first coupling portion 13. Particularly, the gripping edge 17, under the container
1 first closed condition, exhibits a minimum distance D1 (Figure 8) from the storehouse
free edge 6 greater than 2 mm, particularly greater than 3 mm, still more particularly
comprised between 3.5 and 12 mm.
[0187] As it is visible for example in Figures 5 and 24, the undercut portion 16 of the
removable portion 15 comprises at least one hook 18 defining a seat 19 whose concavity
faces at least one of the storehouse 2 lateral walls 4. Particularly, the seat 19
exhibits a substantially "C" shape: the gripping edge 17 delimits the portion of the
seat 19 facing the storehouse 2 free edge 6. More particularly, it is possible to
observe that the gripping edge 17 of the removable portion 15, under the container
1 first closed condition, is interposed between the storehouse 2 free edge 6 and the
respective gripping edge 21 of the first coupling portion 13.
[0188] The attached figures represent, in a non limiting way, a configuration of the removable
portion 15 which exhibits two undercuts 16 placed opposite to each other with respect
to the removable portion 15 itself: the concavities of the respective seats 19 are
opposite to each other and face respective abutment portions 11 of the storehouse
2. With reference to the first coupling portion 13, it is instead possible to observe
that the concavity of the seat 19 of the removable portion 15, under the container
1 first closed condition, faces the concavity of the seat 23 of the respective undercut
portion 20 of the first portion 13.
[0189] As described hereinbefore, the first and second coupling portions 13, 14 of the safety
device 12 are configured for defining a first closed condition substantially defined
by the first engagement/coupling between said portions. Before the first closed condition,
the first coupling portion 13 is placed outside the internal volume 3, while the second
coupling portion 14 lies inside the storehouse 2 (this condition is illustrated in
Figures 2, 3, 24). After, the closure system 7 is guided for the first time inside
the storehouse 2 as illustrated, for example, in Figure 4, 5, 6 and 25: during such
step, the system 12 is configured for defining the container 1 closed condition and
at the same time there is a first engagement between the first and second coupling
portions 13, 14. De facto, during the container 1 first closed condition, the removable
portion 15 hook 18 engages the first portion 13 hook 22: the first closed condition
is illustrated in Figures 1, 7, 8 and 26. More particularly, also during the first
closed condition, the sheet material body of the first coupling portion 13 is configured
for sliding, initially rearwardly the removable portion (the removable portion 15
is interposed between the first coupling portion 13 and the storehouse 2 lateral wall
4) for then passing through the seat 19 and being interposed between the storehouse
2 lateral wall 4 and the second coupling portion 14. As an alternative, the coupling
portion can initially slide forwardly the removable portion 15 for then passing through
the seat 19: under such condition, the second portion 14 is interposed between the
storehouse 2 lateral wall 4 and the first coupling portion 13.
[0190] The container 1 first closed condition is schematically illustrated in Figures 1,
7, 8, 26 and 30. Under such condition, the removable portion 15 hook 18 abuts on and
is stably engaged with the first portion 13 hook 22: under such condition, the first
portion 13 is completely inserted inside the removable portion 15 seat 17 and the
respective undercuts 16 and 20 define a stably engagement condition between the portion
13 and 14.
[0191] The projection 25 carried by the removable portion 15, under the device 7 first closed
condition and before the container 1 first open condition, is distanced from and placed
opposite to the gripping edge 17 with respect to the removable portion 15; particularly
the projection 25 emerges oppositely to the gripping edges with respect to the removable
portion 15 and, as hereinbefore described, emerges from the storehouse 2 free edge
6. De facto, the second portion 14, under the device first closed condition and before
the container 1 first open condition, remains completely inside the volume 3 together
with the removable portion 15: only the removable portion 15 projection 25 emerges
at least partially from the volume 3 and particularly besides the storehouse 2 free
edge 6.
[0192] It is useful to note that the removable portion 15, based on the mode of inserting
the portion 13, can be interposed between the storehouse 2 lateral wall 4 and the
tab inserting portion 10 (condition illustrated in Figure 8) or can be arranged internally
of the volume 3 behind the tab 8 inserting portion 10.
[0193] In case the removable portion 15 is located between the storehouse 2 lateral wall
4 and the tab 8 inserting portion 10, the projection 25, under the device 7 first
closed condition and before the container 1 first open condition, emerges from the
free edge 6 between the tab 8 and the storehouse lateral wall 4 directly facing the
inserting portion 10. Viceversa, in case the removable portion 15 should remain behind
the inserting portion 10, the projection 25 is configured for being arranged internally
of the tab 8 through opening 26; preferably, under such condition, the projection
25 passes through at least partially the through opening 26 and then emerges from
the storehouse 2 free edge 6 and possibly also from the tab 8 closing portion 9 (Figure
31).
[0194] As hereinbefore described, the storehouse 2 can further comprise a recess 27 - preferably
carried by the lateral 4 parallel to the second coupling portion 14 of the safety
device 12 and directly facing the inserting portion 10 - able to substantially define
a free edge 6 depression; the recess 27 enables to aid the projection 25 to emerge
from the free edge 6 following the first closed condition and before the open condition.
De facto, the recess 27 is able to enable both to visualize and give a tactile perception
of the projection 25.
[0195] With reference instead to the control opening 24, it is useful to note - see Figures
1 and 2, for example - that the same is carried by the lateral wall 4 parallel to
the safety device 12 second coupling portion 14; the control opening 24 is advantageously
placed at the safety device 12 removable portion 15 and at the tab 8 inserting portion
10. More particularly, the control opening 24 is placed on the same lateral wall 4
carrying the recess 27: the control opening 24 is distinct and distanced from the
recess 27 and particularly is placed below said opening 24. The control opening 24
is configured to enable visualising the removable portion 15, particularly the first
surface 15a, before the container 1 first open condition (during the container 1 first
closed condition); the control opening 24 is further configured to enable visualising
the inserting portion 10, particularly the first surface 10a, following the container
1 first open condition for giving a visual evidence of a container 1 tampering. In
a preferred but non limiting embodiment of the invention, the control opening 24 is
configured to enable visualising, from the outside, the removable portion 15 and/or
to enable visualising the correct engagement (arming) of the safety device 12 and
particularly the correct insertion/engagement of the first portion 13 with the second
portion 14 and therefore the correct arming of the device 12.
[0196] As hereinbefore described, the safety device 12 is further configured for giving
evidence of a tampering; particularly, engaging the removable portion 15 with the
first coupling portion 13 defines a stable engagement between the storehouse 2 and
closure system 7 which resists the container 1 opening - the user, at the first opening,
notices a substantial resistance to the container opening - for giving a proof that
this latter has not been already opened. The safety device 12, during the first open
condition, is configured for enabling to separate the first removable portion 15 and
therefore the projection 25, from the second coupling portion 14. The first open condition
is for example illustrated in Figure 9: during the system 7 first open condition,
the first coupling portion 13 grips the removable portion 15 (a grip between the hooks
18 and 22) and tears it from the second portion 14.
[0197] Following the first open condition, the device 12 is capable of providing evidence
of a tampering because the system 7 opening is easier: the user does not perceive,
during the opening, a resistance on the inserting portion 10 (see Figures 10 and 22,
wherein it is evident the absence of the removable portion 15). Further, following
the first open condition, the control opening 24 enables visualizing the inserting
portion 10 instead of the removable portion 15 (alternatively, it enables visualizing
the storehouse 2 internal volume): under such condition, the user can easily realize
that the container 1 has been tampered without providing to open the same. Advantageously,
it is possible to differentiate the surfaces 15a and 10a respectively of the removable
portion 15 and inserting portion 10 in order to make easier to acknowledge said surface
and intensify the evidence of a tampering. For example, it is possible to provide
two different colors of the surfaces 15a and 10a: in such way the user can detect
the container 1 tampering just by recognizing the color of the inserting portion 10
rather than on the removable portion 15. Besides the possibility of visually checking
the container 1 tampering, the same can give a proof of a first opening by means of
a missed tactile perception of the projection 25: in this way also sight-impaired
people can check that has been performed a tampering.
[0198] As hereinbefore described, the projection 25 is configured for emerging from the
storehouse 2 free edge 6 (or also just from the recess 27 and/or through opening 26).
Under the container 1 first closed condition and before the first open step, the projection
25 is carried by the removable portion 15 which is also arranged internally of the
storehouse: under such condition, the projection emerges from the free edge 6 and
is easily tactilely perceivable.
[0199] Following the first opening of the container 1, the removable portion 15 separates
from the storehouse 2 (more generally from the container 1) and with it also the projection
25 which is no more tactilely perceivable. The absence of the projection 25 can immediately
give a proof that the container has been tampered also without a visual proof. Figures
31 and 33 illustrate a further embodiment of the safety device 12, which comprises
a control portion 28 of sheet material directly carried by the storehouse 2 and/or
closure system 7; the control portion 28 is configured to place, following the system
7 first closure and before the container 1 first open condition, behind the inserting
portion 10 so that the same is interposed between said control portion 28 and the
storehouse 2 lateral wall 4 directly abutting on the inserting portion 10. Under such
condition, the control portion 28 is entirely contained in the storehouse 2 and directly
covered by the removable portion 15. Specifically, the control portion 28 is configured
to place immediately behind the projection 25 and immediately behind the projection
portion emerging from the free edge 6. De facto, the control portion 28 top is configured
for remaining inside the volume 3 at the storehouse free edge 6. On the top of the
control portion 28, the same has a cavity 29 contactable from the outside via the
though opening 26. More specifically, the cavity 29 defines an open outline exhibiting
a concavity facing the tab closing portion 9, in other words oppositely the internal
volume 3. Still more particularly, the open outline of the control portion 28 cavity
29 defines an outline selected in the group among: a "U, a "V", a "C" outline.
[0200] The control portion 28 is configured to place, following the container 1 first open
condition, behind the inserting portion 10 so that the same is interposed between
said control portion 28 and the storehouse 2 lateral wall 4 abutting on the inserting
portion 10; under such condition, the control portion 28 is entirely contained in
the storehouse and faces the through opening 26 of the closure system 7: without the
projection 25, the control portion 28 cavity is contactable from the outside via the
through opening 26 and is tactilely perceivable for confirming the absence of the
removable portion 15 and for giving therefore evidence of the container 1 tampering.
De facto, the tactile perception of the cavity 29 through the opening 26 can confirm
the absence of the projection 25 and particularly of the removable portion 15 and
can therefore give evidence of the container 1 tampering.
[0201] In the embodiment illustrated in the attached figures, the control portion 28 is
carried, in a non limiting way, directly by the storehouse 2 and comprises a sheet
lying parallelly to the second coupling portion 14; particularly, the control portion
28 is, in a non limiting way, integrally joined and parallel to the second coupling
portion 14 of the safety device 12.
[0202] In a preferred, but non limiting way, embodiment of the invention, the device 12
(portions 13, 14 and 15) is at least partially, particularly completely, made of paper
sheet material (paper or paperboard); the used sheet material exhibits a grammage
comprised between 100 and 500 gr/m
2, particularly comprised between 200 and 400 gr/m
2. Optionally, the paper sheet material used for making the device 12 is as the sheet
material used for making the storehouse 2 and the closure system 7, particularly they
are all obtained from only one paper material sheet. As hereinbefore described, the
container 1 can also be used for housing pharmaceutical, cosmetic and food products.
Under such condition, it can be advantageous covering an internal surface of the device
12 by a plastic material coating, for example a film. The coating has the object of
defining a barrier interposed between the device 1 and products; the coating is further
able to define a water and/or humidity barrier useful for avoiding the weakening and
the structurality loss with a consequent warping of the paper material forming the
device 12. Advantageously, the coating could be an extrusion coating on one side (the
device 12 internal side) or on both sides (the device 12 internal and external surfaces)
of the paper material defining the safety device having values which can for example
vary between 10 and 50 gr/m
2 of the coating material (in other words the polyethylene). The coating plastic material
can be for example selected among the following materials: LDPE, HDPE, PP, PE.
[0203] It is useful to specify that, since the above described solution represents a preferred
but non limiting configuration of the container 1. Indeed, the removable portion 15
could equally form at least part of the first and/or second coupling portions 13,
14. For example, the removable portion 15 could define the respective undercut 20
and therefore the hook 22 of the first coupling portion 13; in such case, during the
first container opening, the removable portion 15 would be configured for separating
from the first portion 13. As hereinbefore described, it is not excluded the possibility
of defining at least one removable portion 15 on the first coupling portion 13 and
at least one removable portion on the second coupling portion 14.
[0204] In a further embodiment non illustrated in the attached figures, the safety device
12 comprises a sheet material tab at least partially made of paper and/of plastic
material: the tab is outwardly engageable with the container 1 following the first
closed condition of this latter and particularly of the system 7. Still referring
to the container 1 first closed condition and before the first open condition of the
same, the tab comprises at least one first constrain portion stably engaged with the
tab 8 closing portion 9, at least a second constrain portion stably engaged with the
storehouse lateral wall and particularly with the wall which, under the system 7 closed
condition, directly faces and abuts on the inserting portion 10. Advantageously, the
first and second constrain portions are stably glued outside the container 1.
[0205] Further, the tab comprises at least one removable portion 15 removably engaged, on
one side, with the first constrain portion and, on the opposite side, with the tab
second constrain portion. The tab outwardly engaging the container 1, defines a "L"
outline and at least one tactilely perceivable projection 25 emerging from the storehouse
2 and/or from the closure system 7. The projection 25 can for example emerge transversally,
particularly normal, from the closing portion 9 and exhibit one of the hereinbefore
described shapes (for example, triangular, square, rectangular, semicircular). The
tab removable portion 15, following the first closed condition and before the container
1 first open condition, is placed and covers at least part of the closure system 7
inserting portion 10.
[0206] The removable portion 15, together with the projection 25, is only engaged with said
first and second constrain portions by weakening lines which form the tab weakened
pre-notched portions. In other words, the removable portion 15 (together with the
projection) is not directly constrained to the container 1 but is directly engaged
only with the first and second constrain portions.
[0207] The removable portion 15, together with the projection 25, is configured for separating
from the first and second constrain portions following a closure system 7 first open
condition after said first closed condition for providing evidence of a container
1 tampering.
[0208] More particularly, during the first open condition of the container 1 and therefore
of the system 7, the constrain portions are configured for remaining engaged (glued)
with the storehouse 2 and closing portion 9; the removable portion 15 is not directly
constrained to the storehouse 2 and system 7: the weakening lines present on the tab
around the removable portion 15 cause the breakage of the tab and the separation of
said removable portion 15 from the respective constrain portions. As hereinbefore
described, the removable portion 15 carries the projection 25 which, separating from
the tab, is no more tactilely perceivable. Following the container first opening,
the tab can therefore give evidence of a tampering by the absence of the removable
portion 25 and therefore of the projection 25.
Process for making a tamper-evident container
[0209] Further, it is an object of the present invention a process for making a tamper-evident
container 1. First of all, the process provides to predispose the storehouse 2 which,
as hereinbefore described, is made of sheet material, optionally paper. Particularly,
such step provides to predispose at least one first sheet 51 comprising at least one
first and one second portions 52, 54 interconnected by a central connecting portion
53. The first sheet 51 further comprises at least one first and one second lateral
connecting portions 55, 56. As it is visible for example in Figures 11, 12, 16, 18,
36-38, the central connecting portion 53 is interposed between the first and the second
portions 52, 54, the first portion 52 is interposed between the first lateral connecting
portion 55 and the central connecting portion 53 while the second portion 54 is interposed
between the second lateral connecting portion 56 and the central connecting portion
53. Each of said portions 52, 53, 54, 55, 56 comprises at least two longitudinal opposite
edges and two end opposite edges: the portions 52, 54, the central connecting portion
53 and said lateral connecting portions 55, 56 are joined along the longitudinal edges
and aligned along only one connecting direction.
[0210] In a preferred but non limiting configuration of the invention, the first portion
52 of the first sheet 51 exhibits a rectangular shape perimetrally delimited by a
lower edge 52a, a first and second lateral edges 52b, 52c and an upper edge 52d. Analogously,
the second portion 54 of the first sheet 51 has a rectangular shape perimetrally delimited
by a lower edge 54a, a first and second lateral edges 54b, 54c and an upper edge 54d.
Advantageously, the first and second portions 52, 54 comprise a sheet having substantially
the same shape and size. The central portion 53 and lateral connecting portions 55,
56 exhibit also rectangular shapes; such portions substantially exhibit the same shape
and/or size and are integrally joined to the portions 52 and 54 of the first sheet
at the lateral edges.
[0211] The step of predisposing the storehouse 2 provides a step of folding the first sheet
51 at the lateral edges of the portions 52 and 54. The steps of forming the storehouse
2 are schematically illustrated in Figures 12-15, 39, 40 and initially provide to
fold a lateral connecting portion, for example the portion 55, with respect to the
first portion 52 and on approach to the second portion 54 (Figures 12 and 40): for
example, it is possible to provide to fold the longitudinal connecting portion 55
so that this latter can define, in cooperation with the portion 52, a substantially
"L" shape. Then, the process provides, for example, to fold the central portion 53
with respect to the first portion 52 and on approach to the portion 55 that was already
folded (see Figure 13, for example): for example it is possible to provide to fold
the central portion 53 so that this latter can define, in cooperation with the portion
52, a substantially "L" shape. Successively, it is for example possible to provide
to fold the second portion 54 with respect to the central portion 53 and on approach
to the first portion 52 (see Figure 14, for example): for example, it is possible
to provide to fold the second central portion 54 so that this latter can define, in
cooperation with the central portion 53, a substantially "L" shape. For completely
forming the storehouse 2, the process provides to fold the remaining longitudinal
connecting portion, for example, the portion 56, with respect to the second portion
54 so that it is possible to join said lateral connecting portions 55, 56. For holding
the storehouse 2 in the folded three-dimensional shape, the process can provide, in
a non limiting way, to apply a predetermined quantity of glue 72 (Figure 15) only
the longitudinal connecting portions 55, 56 able to abut on each other: joining said
portions enables to lock the storehouse 2 in the folded configuration.
[0212] It is useful to specify that the step of predisposing the first sheet 51 can provide
a packing step which enables to define, on the same sheet, folding lines coinciding
with the longitudinal lateral edges of the portions of said first sheet 5. De facto,
the steps of folding the first sheet portions are performed just along the longitudinal
lateral edges of said portions which are packed in order to make easier the movement
(folding) thereof.
[0213] The step of predisposing the first sheet 51 further provides at least a step of forming
on the same 51 at least one through notch 69 placed on the first and/or second portions
52, 54 and which is configured for defining said control opening 24. The notch 69
is substantially executed at the lower and/or upper edges of at least one of said
portions 52, 54. Further, the step of predisposing the first sheet 51 provides at
least one step of forming on the same 51 at least a through groove 75 (see Figures
36-38, for example), placed on the first and/or second portions 52, 54 which is configured
for defining the recess 27. The groove 75 is substantially obtained at the lower and/or
upper edges of at least of said portions 52, 54. Advantageously but in a non limiting
way, the groove 75 is obtained on the same sheet portion on which the notch 69 is
defined and particularly above this latter. Specifically, the through groove 75 is
defined at least on a transversal edge of the first or second portion 52, 54 of the
first sheet 51; in Figures 36-38 the groove 75 is defined at the transversal edges
of the second portion 54. The through groove 75 defines an open outline having a substantially
"C" shape (Figure 37), or a "U" shape (Figure 36), or a "V" shape. Advantageously,
the first sheet 51 is entirely made of paper material, exhibiting a grammage comprised
between 100 and 500 gr/m
2, particularly comprised between 300 and 400 gr/m
2.
[0214] Further, the process provides to predispose the closure system 7. Such step provides
to predispose at least one second sheet 57, advantageously, integrally joined to the
first sheet 51, particularly at an end edge of the first and/or second portions 52,
54 of the first sheet 51 (Figures 11, 36-38). The second sheet 57 comprises at least
one first and one second portions 58, 59 integrally joined to each other: the first
portion 58 of the second sheet 57 is connected to the first sheet 51 so that said
first portion 58 is interposed between the second portion 59 of the second sheet 57
and the first sheet 51. The attached figures illustrate a preferred but non limiting
configuration of the invention wherein it is provided to predispose two second sheets
57 engaged with the first sheet 51 and placed opposite to this latter. The second
sheet 57 is for example directly connected to the upper edge 52d and/or lower edge
52a of the portion 52 of the first sheet 51. Figures 11, 16, 18 and 36 illustrate,
in a non limiting way, an embodiment wherein it is provided to form the two sheets
57 respectively on the lower 52a and upper edges 52d of the portion 52. Figures 23
and 36 illustrate an alternative embodiment wherein a second sheet 57 is directly
connected to the upper edge 52d of the portion 52 while a second sheet 57 is directly
connected to the lower edge 54a of the second portion 54. Advantageously, the second
sheet 57 is integrally joined to the first sheet to define only one sheet; particularly,
also the second sheet 57 is made of paper material, particularly of a paper material
sheet having substantially the same characteristics as the first sheet 51.
[0215] The step of predisposing the second sheet 57 can further provide at least one step
of forming on the same a through notch 74 (Figures 36-38) which is able to define
the through opening 26 of the closure system 7. The through notch 74 can be defined
on the first and/or second portions 58, 59 of the second sheet 57; in a preferred
but non limiting embodiment of the invention, the notch 74 is partially defined on
the first and partially on the second portions 58, 59 of the second sheet 57 without
interruptions to define a single closed outline notch. Still more specifically, the
through notch 74 defines a closed perimetral outline exhibiting at least one shape
selected in the group of the following shapes: square, rectangular, diamond, circular,
elliptical, semicircular, triangular. The attached figures illustrate a non limiting
embodiment of the invention wherein the notch exhibits a rectangular shape. Advantageously,
the second sheet 57 exhibits a grammage between 100 and 500 gr/m
2, particularly comprised between 300 and 400 gr/m
2.
[0216] Further, the process provides the steps of folding the first and second portions
58, 59 of the second sheet 57 for forming respectively the closing portion 9 and inserting
portion 10 of the closure system 7. The step of predisposing the closure system 7
further provides a sub-step of predisposing at least one third sheet 60 exhibiting
at least one portion 61 connected at least to one central and/or lateral connecting
portions of the first sheet 51 and emerging from this latter from the same side from
which the second sheet 57 emerges. Advantageously, the third sheet provides four portions
61 integrally joined to the first sheet 51. Two portions 61 are connected to the central
portion 53 and emerge from this latter opposite to each other along respective end
edges (emerging from the first sheet 51 from the same side from which the second sheet
57 emerges).
[0217] Two further portions 61 are connected to the longitudinal connecting portion 55 or
56 (Figure 11 illustrates, in a non limiting way, a configuration where the further
two portions 61 are carried by the portion 56) and emerging from this latter opposite
to each other along respective end edges (emerging from the first sheet 51 from the
same side from which the second sheet 57 emerges). Each portion 61 is made of a flat
sheet material, particularly a paper sheet material, and exhibits a substantially
square or trapezoidal shape. Advantageously, also the third sheet 60 is made of paper
material, particularly a paper material sheet, having substantially the same characteristics
as the first and second sheets 51, 57. Advantageously, the third sheet 60 exhibits
a grammage between 100 and 500 gr/m
2, particularly comprised between 300 and 400 gr/m
2. Further, the process comprises the step of folding the third sheet 60 portion 61
towards the storehouse internal volume to form the container 1 abutment portion 11.
[0218] Advantageously, first of all the process provides to fold the first sheet 51 to define
the storehouse 2; then the third sheet 60 is folded to define the abutment portion
11. Following or simultaneously with the third sheet 60 folding, the second sheet
57 is folded to define said closure 9 and inserting portions 10.
[0219] Further, the process provides to predispose the safety device 12 which provides at
least the sub-step of predisposing a fourth sheet 62 comprising at least one portion
63 integrally joined to the second portion 59 of the second sheet 57 and/or to the
portion 61 of the third sheet 60. The fourth sheet 62 portion 63 is also made of sheet
material, particularly of paper sheet material, and longitudinally emerges from the
second and/or third sheets 57, 60 opposite to the first sheet 51: the fourth sheet
62 portion 63 is configured for defining the container 1 first coupling portion 13.
The attached figures illustrate, in a non limiting way, a configuration of the fourth
sheet 62 which is directly connected (emerging away from) to the second portion 59
of the second sheet 57. However, it is not excluded the possibility of forming a fourth
sheet 62 emerging from the third sheet 60 away from the first sheet 51 (this configuration
is not illustrated in the attached figures).
[0220] More specifically, the step of forming the portion 63 of the fourth sheet 62 provides
at least the following sub-steps:
- forming, as a prolongation to the second portion 59 of the second sheet 57, a flat
sheet substantially parallel to the second sheet 57, the prolonging sheet emerges
from the second portion 59 opposite to the first portion 59 of the second sheet 57;
- forming at least one undercut 71 able to define the first coupling portion 13 of the
container 1.
[0221] The undercut 71 substantially defines on the fourth sheet, a seat configured for
defining the undercut 20 of the first coupling portion 13. Advantageously, the step
of forming the prolongation provides to form at least two undercuts 71 opposite to
each other with respect to the fourth sheet 62 itself and which are configured for
defining the respective undercuts 20 of the first coupling portion 13. As described
hereinbefore, also the fourth sheet 62 is made of paper material, particularly of
a paper material sheet, having substantially the same characteristics as the first,
second and third sheets 51, 57, 60. Advantageously, the fourth sheet 62 exhibits a
grammage comprised between 100 and 500 gr/m
2, particularly comprised between 300 and 400 gr/m
2.
[0222] The step of predisposing the safety device 12 further provides at least the sub-step
of predisposing a fifth sheet 64 comprising at least a portion 65 integrally joined
to the first sheet 51. In a non limiting configuration of the invention, illustrated
in Figures 11, 18 and 37, the fifth sheet 64 emerges laterally from the first sheet
51 beside the portion 55: this latter portion is interposed between the fifth sheet
64 and the first sheet 51 portion 52. In such a configuration, the process, during
the step of forming the storehouse 2, provides to fold the portion 65 of the fifth
sheet 64, to define said second coupling portion 14, immediately after the longitudinal
portion 55 folding: in such way, after having folded the portions 53, 54 and 56, the
fifth sheet 64 is positioned inside the storehouse 2. A further configuration is for
example illustrated in Figure 23, in which the fifth sheet 64 is connected to and
emerges away from the first portion 52 of the first sheet 51 and/or from the second
portion 54 of the first sheet 51. In such configuration, the step of folding the portion
65 of the fifth sheet 64, to define said second coupling portion 14, can be performed
before, during or after the step of forming the storehouse 2. In both the configurations
of the fifth sheet 64, following the step of folding the portion 65, this latter is
configured to place in the storehouse internal volume 3 to define said coupling portion
14.
[0223] The fifth sheet 64 portion 65 is also made of sheet material, particularly paper
sheet material. More particularly, the step of forming the fifth sheet 64 portion
65 provides at least the following sub-steps:
- forming, as a prolongation to the first sheet 51, a flat sheet substantially parallel
to the second sheet 57;
- forming on said sheet at least one undercut 70 adapted to define the second coupling
portion 14 of the container 1. The undercut 70 substantially defines a seat (see for
example Figure 11) able to receive the undercut 71 of the fourth sheet 62; the undercut
70 is de facto configured for defining the undercut 16 of the second coupling portion
14. Advantageously, the step of forming the prolongation provides to form at least
two undercuts 70 opposite to each other and which are configured for defining the
respective undercuts 16 of the second coupling portion 14. As hereinbefore described,
also the fifth sheet 64 is made of paper material, particularly a paper material sheet,
having at least the same characteristics as the fourth sheet 62. Advantageously, the
fifth sheet 64 exhibits a grammage comprised between 100 and 500 gr/m2, particularly comprised between 300 and 400 gr/m2. In a preferred but non limiting embodiment of the invention, the first, second,
third, fourth and fifth sheets 51, 57, 60, 62, 64 are integrally joined to form a
single blank sheet 50 (this condition is illustrated in Figures 11, 16, 23); the blank
sheet 50 is at least partially, particularly entirely, made of paper sheet, optionally
the blank sheet 50 exhibits a grammage comprised between 100 and 500 gr/m2, particularly comprised between 300 and 400 gr/m2.
[0224] The process further provides a step of forming, on the portions 63 and/or 65, respectively
of the fourth and fifth sheets 62, 64, at least a further portion 66 integrally joined
to said portion 63, 65 by a weakening line 67: the further portion 66 defines the
undercut 70 and/or 71 and is configured for defining the container 1 removable portion
15. This step of forming the further portion 66 substantially provides a sub-step
of packing and/or notching the fourth and/or fifth sheets 62, 64 for forming on this
latter a weakening line 67 (see Figure 11, for example) which is able to define a
portion of the sheet separable (tearable) from the main body of the sheet. The attached
figures illustrate a non limiting configuration of the invention, in which the further
portion 66 is carried by the fourth sheet 62 so that, at the end of the packing and/or
notching steps and the following sheets folding step, the removable portion 15 is
carried by the second coupling portion 14 as illustrated in the attached figures showing
the container 1. However, as hereinbefore described, the removable portion 15 can
be carried by the first coupling portion 13 or by both the portions 13, 14. For defining
the removable portion 15 on the coupling portion 13, the process should provide a
step of packing and/or notching the fourth sheet 62 so that the further portion 66
could be defined (integrally joined to) on the portion 63 (this condition is not illustrated
in the attached figures). The process provides to form the further portions 66 as
many as the present second sheets 57 and therefore as many as the closure systems
7 provided on the container 1. Figures 11, 16, 23, 36-38 illustrate a preferred but
non limiting configuration of the invention, in which there are two fourth sheets
62 respectively integrally joined to the two second sheets 57, in order to form first
coupling portions 13; therefore there are at least two further portions 66 carried
by a single fifth sheet 64 (Figures 11 and 16) or by two fifth distinct sheets 64
(Figure 23): the portions 66 are configured for defining two removable portions 15
which are able to cooperate with the two respective first coupling portions 13 of
the fourth sheet 62.
[0225] The step of predisposing the safety device 12 further provides a step of forming
on the removable portion the tactilely perceivable projection 25 emerging from the
storehouse 2 and/or from the closure system 7: the removable portion 15, together
with the projection 25, is configured for separating from the safety device 12 following
a first open condition of the closure system 7 following said first closed condition
for providing evidence of a container 1 tampering. More specifically, the step of
predisposing the further portion 66 provides to form at least one bulge 73 emerging
from the further portion 66 - of the fourth and/or fifth sheets 62, 64 - and placed
oppositely with respect to the undercut 70 of the further portion itself. The bulge
73 is able to define the removable portion 15 projection 25: the removable portion
projection 25, following the container 1 first closed condition, emerges from the
storehouse 2 free edge 6 and/or from the closure system 7 outside the internal volume
3. De facto, the bulge 73 is distanced from and opposite to the undercut 70 so that
following the step of folding the fifth sheet inside the storehouse 2, the undercut
is completely housed in the volume 3 while the projection emerges at least partially
from the free edge 6 and/or recess 27. De facto, as hereinbefore described, the projection
25 is distanced from and placed oppositely to the gripping edge 17 with respect to
the removable portion 15: the projection 25 emerges oppositely to the gripping edge
17 with respect to the removable portion 15.
[0226] Further, the process can comprise to form, on the fourth and/or fifth sheets carrying
the further portion 66, an additional portion 76 of sheet material foldable above
the further portion 66 for defining the control portion 28. De facto, the additional
portion 76 represents a prolongation of the portion 66 and which defines a substantially
end portion of the portion 66. As it is visible for example in Figure 36, the portion
66 is interposed between the additional portion 76 and the second portion 54 of the
first sheet 51; the additional portion 76 is foldable above the portion 54 together
with the portion 66: then, the additional portion 76 is again folded above the portion
66 so that the cavity 29 of the control portion 28, in the three-dimensional configuration
of the container 1, can be located immediately behind the projection as for example
illustrated in Figure 40.
[0227] Advantageously, the sheets are obtained from a single flat sheet, particularly of
paper material, which is die cut for defining the blank 50 comprising the above described
sheets 51, 57, 60, 62 and 64. The die cutting step, besides defining the contour of
the blank, is configured for packing the sheet for perimetrally delimiting the single
sheets, for example by defining the end connection edges of the sheet and along which
the folds should be executed in the following. Further, the die cutting step enables
to notch the portions 52 and 54 for defining at least one of the following elements:
the control opening 24, bulge 73, notch 74, groove 75, undercuts 70 and/or 71. During
the die cutting step there is simultaneously the packing and/or notching of the fourth
and/or fifth sheets for defining the weakening line 67 (or the plurality of weakening
lines 67) for forming the further portion 66. Substantially, by a single die cutting
step it is possible to define the flat blank 50 complete of all the above described
sheets 51, 57, 60, 62, 64.
[0228] Further, the process can provide a step of predisposing a container 1 arranged in
a compacted shape as illustrated in Figure 17. Particularly, following the single
blank 50 formation, the process provides the steps of folding the first sheet 51 in
order to couple the portions 55 and 56. Then, the first and second portions 52, 54
are approached and located at least partially in contact with each other. From such
condition, it will be sufficient to lift the portions 55 and 56, and also the central
portion 53 for arranging the storehouse 2 in the three-dimensional shape with the
closure system 7 not already folded (this condition is illustrated in Figures 2 and
3). From such condition, the container 1 is ready for receiving the products and then
for being closed for the first time: during the container 1 first closure, there is
the coupling of the portions 13 and 14 and therefore the safety device 12 is "armed"
or activated. In case there are two distinct through openings 5, the process can provide
to close a system 7 (arming only one safety device 12), to insert the products in
the storehouse 2 and to completely close the container 1 by closing the second and
last systems 7 (arming the second and last safety devices 12).
